This choropleth map displays world countries colored by income group, with a legend showing the ordinal color scale. Built with D3 v5, it uses `d3.geoMercator` for projection, `d3.geoPath` to render geographic features from TopoJSON world-atlas data, and `d3.scaleOrdinal` with `schemeReds` for color encoding. Interactive zooming is enabled via `d3.zoom`. A custom color legend with animated circles transitions updates smoothly, and hover effects highlight individual countries.

D3 Course Code Along - Choropleth Map

This choropleth map colors world countries by income group, using a red sequential color scale with a natural Earth projection. The visualization includes interactive zooming and panning, plus hover effects that highlight individual countries on mouseover. Built with D3 v5, it loads TopoJSON country boundaries from the World Atlas and TSV metadata to join income classifications to each country. Animated color legend transitions update dynamically, while the globe outline is rendered using d3.geoPath with a sphere geometry.

D3 Course Code Along - Choropleth Map

A choropleth map colors world countries by income group using a natural Earth projection, with a color legend and zoom interaction. It uses `d3.geoNaturalEarth1` and `d3.geoPath` to render the GeoJSON features, while `d3.scaleOrdinal` and `schemeReds` map categorical values to colors. The legend updates with a transition, and data comes from World Atlas TopoJSON and TSV files. Hovering highlights countries, and mouse-wheel zoom is supported via `d3.zoom`.

D3 Course Code Along - Choropleth Map

This choropleth map visualizes global income groups using a natural Earth projection, with countries colored according to their income classification. The map is rendered as SVG paths generated by `d3.geoPath` from TopoJSON data loaded from World Atlas, combined with TSV metadata. A custom color legend displays the ordinal color scale using `d3.scaleOrdinal` with reds, and a zoom interaction allows viewers to pan and scale the map. Animated transitions with `transition.duration` update the legend circles when the data domain changes.

Fork of D3 Course Code Along - Choropleth Map

This interactive choropleth map colors countries by income group, with a color legend that animates its circles and uses sequential reds from d3.scaleOrdinal. Built with d3.v5 and topojson, it projects world atlas data using d3.geoNaturalEarth1 and renders countries as SVG paths via d3.geoPath. A zoom tool from d3.zoom is applied, and hover effects highlight individual countries, while data is loaded from unpkg-hosted TSV and TopoJSON files.

D3 Course Code Along - Choropleth Map with Clickable Legend

This choropleth map colors countries by income group using a categorical color scale. A clickable legend filters the map, dimming unselected categories to 10% opacity while highlighting the chosen group. Built with D3 v5, it uses d3.geoPath with a d3.geoNaturalEarth1 projection to render country boundaries from TopoJSON data. The visualization also incorporates d3.zoom for interactive panning and zooming, and animates the legend’s color transitions with d3.transition.

Fork of D3 Course Code Along - Choropleth Map

A choropleth map of world countries colored by income group, rendered with a Natural Earth projection. The visualization loads world-atlas TopoJSON data via `d3.json`, projects it with `d3.geoPath`, and colors each country using a sequential red scheme from `d3.schemeReds` based on a categorical `d3.scaleOrdinal` scale. An interactive legend built with custom SVG `circle` and `text` elements shows the color categories. The map supports zooming via `d3.zoom` and includes hover effects that highlight countries.

Choropleth Map

This choropleth map colors world countries by income group using a categorical color scale with a spectral scheme. The visualization supports zooming and panning through d3.zoom, with country names and income groups revealed via tooltips on hover. Built with d3.geoPath and geoNames from the world-atlas TopoJSON dataset, it renders as SVG paths over a blue sphere. A custom color legend component displays the ordinal scale’s domain, while hover interactions highlight individual countries in red.

Fork of D3 Course Code Along - Choropleth Map

This interactive choropleth map visualizes countries color-coded by income group on a natural Earth projection. A legend with animated transitions updates when the color scale changes. The visualization uses d3.geoPath with TopoJSON data from the World Atlas, and builds the map with SVG paths. Hover effects highlight individual countries, while zoom and pan are enabled through d3.zoom. World population data from CSV files supports additional context.
